The K-beauty face mask with a 20,000 person waitlist is adding a new product, and it's guaranteed to become a skin-care staple

The social media post displays a creamy, pink product that some are speculating to be a daily moisturizer.

The reveal is highly anticipated after the success of Glow Recipe's classic Watermelon Glow Sleeping Mask.

Glow Recipe, an e-commerce Korean beauty destination founded by Shark Tank alums Sarah Lee and Christine Chang, sent beauty babes into a frenzy when it launched its cult classic Watermelon Glow Sleeping Mask ($45) in May 2017. The sweet-smelling, radiance-boosting gel moisturizer softened and smoothed the complexions of thousands, making it an instant beloved product in clear skin routines. So when the brand posted on their Instagram on Monday teasing a new product in their popular watermelon line, fans went crazy.

The Instagram post shows what looks like a creamy, lightweight pink product, which begs the question: Is this new beauty product a daily moisturizer? Could it be a face wash? Commenters weighed in, sharing their guesses for what they hoped the upcoming launch would be.

While we'll have to wait until Thursday for the official announcement from the Glow Recipe gals, here's what we do know: This product-to-be already has garnered a ton of attention, and the watermelon line already has become a skincare staple. Whatever is about to come to market is going to make a big splash — that's for sure.
